APPARATUS FOR REGULATl NG THE ADMIXTURE 0F CARBURETED AND UNCARBURETED GAS FOR ILLUMINATING PURPOSES.

SPECIFICATION forming part of Letters Patent No. 332,088, dated December 8, 1885.

Application filed September 29, 1885. Serial No. 178,562.

To all whom it may concern:

Beitknown that LWALTER J. KIDD, a sub ject of the Queen of Great Britain, residing at Newark, in the county of Essex and State of New Jersey, have invented new and useful Improvements in Apparatus for Regulating the Admixture of Oarbureted and Uncarbureted Gas for Illuminating Purposes, of which the following is a specification.

In the use of devices for enriching illumihating-gas by mixing with it the heated vapor of naphthaline or other carbureting material it is often desirable to regulate the relative proportions of carbureted and uncarbureted gas supplied to the gas burner or burners,'or, in other words, to providea means of controlling or regulating the fiow of uncarbureted gas in contact with the vaporized carbureting material, and to supply a definite proportion of uncarbureted gas directly to the burners or burner-tubes, whereby said gases are mingled in varying quantities with the effect of producing an illuminating mixture of any desired quality immediately prior to its consumption at the burner.

To this end my invention consists in the combination, with gas-burners supported by a suitable tubular casing or chamber and a carbureting-vessel attached to the lower end of said casing, of a gas-supply pipe or tube extending through the easing into the carbureting-vessel, and provided with openings for admitting a direct access of uncarbureted gas to the burners, and with a check, contraction, or valve for controlling the flow of gas to the carbureting-vessel.

The invention also consists in certain peculiarities in the construction and combination of parts, as hereinafter more fully set forth.

In the annexed drawings, Figure 1 is a sectional elevation of a gasenriching apparatus embodying one form of my improvements for controlling the admixture of carbureted and uncarbureted gas, and Fig. 2 represents a modified construction of parts involving the same principle of operation.

Referring to these drawings, the numeral 1 designates the supply-pipe of a chandelier. This pipe may be formed with a bend, coil, or convolution, as shown in Fig. 1, to produce a (No model.)

superheating gas chamber, 2,,above the burners, or said gasheating chamber 2 may be made in disk form, as represented in Fig. 2. In the latter case the gas heating chamber will inclose a horizontal plate or deflector, 3, supported in any convenient manner, with a space above, below, and around its edge to afi'orda circuitous passage for the gas through said heating-chamber. The gas-heating chamber 2, however made, communicates through a pipe, 4, with a tubular chamber or casing, 5, which supports the burner-tubes 6 and carbureting-vessel 7, the latter being detachably secured to thelowerend of said casing beneath the, burners.

It will be seen by referring to the drawings that the pipe 4 is secured to the upper end of the casing 5 and extends vertically downward through said casing and into the carburetingvessel. Opposite the point where the gasburners and their supporting-casing are con nected the pipe 4 is provided with one or more small openings, 8,the size and number of which can be varied as desired. These openings 8 afford a direct means of access for the passage of uncarbureted gas to the burners without passing through the carburetingvessel. By varying the size or number of the openings 8 a greater or less supply of uncarbureted gas will be provided. The pipe or tube4 is provided below the openings 8 with means for retarding, controlling, or regulating the flow of uncarbureted gas through said tube to the carbureting vessel. This may be done by contracting the diameter of the tube 4 at its lower end, 9, as shown in Fig. 1, or the diameter may be reduced at any other point, either permanently or by means of a valve, damper,

or cook, 10, as shown in Fig. 2, by which the flow of gas through the carbureting-vessel can be regulated at will. The relative quantities of carbureted and uncarbureted gas delivered to the burner can thus be readily regulated with the effect of varying the quality of gas to be consumed. The lower end of the casing 5 is provided with an internally-screwthreaded collar, 11, for engaging the externally-threaded neck 12 of the earburetingvessel 7, the latter being thus detachably connected to the burner-support.

It is obvious that by making the carbureting-vessel detachable it need not be provided with special openings for supplying or refilling it, as the neck 12 serves not only as a means of connecting with the burner-casing 5 and as apassage-way for gas, but also as an inlet through which the carbureting material is introduced after the vessel has been detached.

The carbureting-vessel 7 is partly filled with uncarbureted gas in a heated condition de scends through. the pipe 41 and enters the carbureting-vessel, where it comes in contact with and gradually vaporizes the hydrocarbon material contained in said vessel. By mingli ng with these hydrocarbon vapors the heated gas is gradually 'carbureted and passes upward through the tubular casing 5 to the burners, becoming mixed on its way with the uncar bnreted gas delivered through the openings 8 in the supply-pipe. The contraction or check 9 or the valve or damper 10, when partly closed, serves to regulate the quantity of gas passed through the carburetingvessel. By means of the valve, cook, or damper 10 the quantity of gas admitted to the carburetingvessel in contact with its vaporized contents can be controlled at will, so as to vary the quality or richness of the mixed gas as may be desired.

The construction of the gas-heating chamber 2 may be varied in several ways.

The form of beater shown in Fig. l is simple, cheap, and effective, requiring only the formation of a bend or coil in the gas supply pipe. The form shown in Fig. 2, with inclosed deflecting-plate 3,.a'ffordsa more extended heatingsurface for the gas while it is passed in a circuitous course to the carbureting-vessel.

It will be understood that I do not claim heating the unca rbureted gas before conductiug it to the carbureting-vessel; nor do I broadly claim controlling the admission of gas to the burners and carbureting-vessel.

Herctofore in devices for enriching illuminating-ga's an interior pipe has been provided with side openings for admitting gas to the burners, and these side openings have been closed by an adjustable valve, no means being provided, however, for cutting off the flow of gas to the carburet-ing-vessel independent of controlling its flow to the burner. Myinvention differs from this in that the apertures 8 are alwaysv openfor gas to pass through, and

it is only the degree of the contraction of the pipe or tube tbel-ow said apertures, or the extent to which said pipe or tube is closed by the valve '10, that regulates or controls the flow of gas through the tube 4 to the carbureting-vessel or to the burners direct.

WVhat I claim ist 1. In an apparatus 'for enriching gas, the co 'nbination, with a gas-burner, acarburetingvessel, and a tubular chamber or casing for connecting and supporting said burner and vessel, of a 'gassupply tube passed through said casi ng into the ca-rlnireting-vessel and p rovided with one or more side openings for admitting gas direct to the burner, and with a valve located below said openings for the purpose of regulating theilow of to the car bnreting-vessel, substantially as described.

The combination, with the chamber or casing 5, gas-burner 6, and carbi'ireting-vessel 7, of the pipe 4, having side openings, 8, and provided with a valve, 10, located beneath said opening, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
